The Diocese of Frascati (Lat.: Tusculana) is a suburbicarian see of the Holy Roman Church and a diocese of the Catholic Church in Italy, based at Frascati, near Rome. The bishop of Frascati is a Cardinal Bishop; from the Latin name of the area, the bishop has also been called Bishop of Tusculum. [upper-alpha 1] Tusculum was destroyed in 1191. The bishopric moved from Tusculum to Frascati, a nearby town which is first mentioned in the pontificate of Pope Leo IV. [1] Until 1962, the Cardinal-Bishop was concurrently the diocesan bishop of the see in addition to any curial duties he possessed. Pope John XXIII removed the Cardinal Bishops from any actual responsibility in their suburbicarian dioceses, and made the title purely honorific.

Diocese of Rome Diocese of the Catholic Church in Rome, Italy

The Diocese of Rome is a diocese of the Catholic Church in Rome. The Bishop of Rome or the Roman Bishop is the Pope, the Supreme Pontiff and leader of the Catholic Church. As the Holy See, the papacy is a sovereign entity with diplomatic relations, and civil jurisdiction over the Vatican City State located geographically within Rome. The Diocese of Rome is the metropolitan diocese of the Province of Rome, an ecclesiastical province in Italy. The first Bishop of Rome was Saint Peter in the first century. The incumbent since 13 March 2013 is Pope Francis.

Catholic Church Largest Christian church, led by the Bishop of Rome

The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with approximately 1.3 billion baptised Catholics worldwide as of 2017. As the world's oldest continuously functioning international institution, it has played a prominent role in the history and development of Western civilisation. The church is headed by the Bishop of Rome, known as the pope. Its central administration, the Holy See, is in the Vatican City, an enclave within the city of Rome in Italy.

Italy republic in Southern Europe

Italy, officially the Italian Republic, is a European country consisting of a peninsula delimited by the Italian Alps and surrounded by several islands. Located in the middle of the Mediterranean sea and traversed along its length by the Apennines, Italy has a largely temperate seasonal and Mediterranean climate. The country covers an area of 301,340 km2 (116,350 sq mi) and shares open land borders with France, Slovenia, Austria, Switzerland and the enclaved microstates of Vatican City and San Marino. Italy has a territorial exclave in Switzerland (Campione) and a maritime exclave in the Tunisian Sea (Lampedusa). With around 60 million inhabitants, Italy is the fourth-most populous member state of the European Union.


Relationships during the 17th century

Like other dioceses close to Rome, Frascati became a bishopric of choice for Cardinals of powerful papal families during the 17th century; a period known for its unabashed nepotism. Frascati Bishops of that era were significantly intertwined:

Rome Capital city and comune in Italy

Rome is the capital city and a special comune of Italy. Rome also serves as the capital of the Lazio region. With 2,872,800 residents in 1,285 km2 (496.1 sq mi), it is also the country's most populated comune. It is the fourth most populous city in the European Union by population within city limits. It is the centre of the Metropolitan City of Rome, which has a population of 4,355,725 residents, thus making it the most populous metropolitan city in Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of the Tiber. The Vatican City is an independent country inside the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states.

Nepotism refers to granting jobs to one's relatives in various fields, including business, politics, entertainment, sports, religion and other activities. The term originated with the assignment of nephews to important positions by Catholic popes and bishops. Trading parliamentary employment for favors is a modern-day example of nepotism. Criticism of nepotism, however, can be found in ancient Indian texts such as the Kural literature.

Odoardo Farnese (cardinal) Catholic cardinal

Odoardo Farnese was an Italian nobleman, the second son of Alessandro Farnese, Duke of Parma and Maria of Portugal, known for his patronage of the arts. He became a Cardinal of the Roman Catholic Church in 1591, and briefly acted as regent of the Duchy of Parma and Piacenza for his nephew Odoardo from 1622 to 1626.

Odoardo Farnese, Duke of Parma Duke of Parma and Piacenza from 1622 to 1646

Odoardo Farnese, also known as Odoardo I Farnese to distinguish him from his grandson Odoardo II Farnese, was Duke of Parma, Piacenza and Castro from 1622 to 1646.

Wars of Castro

The Wars of Castro were a series of conflicts during the mid-17th century revolving around the ancient city of Castro, which eventually resulted in the city's destruction on 2 September 1649. The conflict was a result of a power struggle between the papacy – represented by members of two deeply entrenched Roman families and their popes, the Barberini and Pope Urban VIII and the Pamphili and Pope Innocent X – and the Farnese dukes of Parma, who controlled Castro and its surrounding territories as the Duchy of Castro.

  3. Giovanni Romano (contemporaries did not call him Marsicano) became a monk at the Abbey of Bec under the well-known Anselm. He became a Canon of Beauvais. Pope Urban II named him Abbot of San Salvatore in Talese, and, in 1099, Pope Paschal II named him Bishop of Tusculum. Around one-third of Pope Paschal's appointments to the College of Cardinals were monks. In 1101 Cardinal Giovanni was sent as Papal Legate to England. In 1108 the Pope appointed him his Vicar for Rome while he travelled to Benevento. In 1111, he and Bishop Leo Marsicano of Ostia organized the resistance against Emperor Henry V, who had just captured the Pope and most of the cardinals. In March 1119 he attended a Synod in Benevento. He died shortly thereafter.

On 13 June 1405 he was promoted to the See of Tusculum (Frascati) by Pope Benedict XIII of the Avignon Obedience. He participated with most of the cardinals of the Avignon and the Roman Obediences in the Council of Pisa and the election of Pope Alexander V. He was Major Penitentiary. He died on 9 November 1415.
